CLARIFICATIONS
1. Note to General Contractors and alternative suppliers of ice rink equipment: The size,quantity and listed material and performance specifications of the chiller equipment(chillers themselves & glycol pumps, etc.), as well as the combination drains, removablecurb, piping, etc., were all intentional selections/decisions. Any significant deviationsfrom the specified equipment will not necessarily be acceptable to Owner. For example,utilizing five (5) identical 10-Ton individual chillers in parallel with two (2) identical glycolpumps was a conscience decision by Owner. Supplying a single 50-ton chiller (or othersuch deviation) in lieu of the five (5) identical units is not satisfactory and would berejected during the shop drawing phase, at no change of cost or responsibility to theOwner.
Attachments
1. Revised Plan Sheet A0.8 and U0.2.
All bidders shall acknowledge receipt and acceptance of this addendum by entering the addendum number on the appropriate space of the submitted Bid Form.
